Application filed March 10, 1522 To (ZZZ whom it may concern:

Be it known that we, HENRY KRUG and Josnrrr Donn, both citizens of the United States of America, and residents otCincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Improvement in lVindow-Sash Locking and VentilatingDevices, of which the following is a specification.

Our invention relates to window ventila tors, and has for one of its objects to regulate the ingress of air through the spacingarrangement of the meeting-rails of the sasl1-n1e1nbers by means of detachable clamping devices and suitable top and bottom spacing-plates, wherein the adjustable mechanism of said clamping devices Will position the "free-end portion of the meetingrails in predetermined points to allow the current of air to freely pass through the draft openings.

Another object of this invention is to provide a rigging which is simple in construction, effective and positive in operation, and comprises a structural combination for a ready and substantial connection with the sash-members.

In the accompanying sheet of drawings, Figure 1 is a sectional fragmentary vertical section of a window, showing the two sashes thereof and the attached air-regulating device; Fig. 2,-an elevation of the regulating device detached; Fig. 3, an enlarged perspec tive of the sliding, segmental, registering plate or hub; Fig. 4, an enlarged perspec tive View of the angular plate or base-member; Fig. 5, an enlarged perspective view of one form of spacing-plate adapted for use with our invention herein; Fig. 6, an elevation of another form or a modification of the said spacing-plate; Fig. 7, a plan View of Fig. 6, showing the interposed connecting-plate; and Fig. 8, a horizontal section, on the line 88, of Fig. 3. Mounted on the external body-portion of the sash casing 1 is a series of staples 2 in spaced relation to each other, slidably-engaging the inturned-end hooks 3 of the right-angled bar-arm 4L. Slidably-arranged upon the vertical portion of said bar-arm 4 is a longitudinally-disposed semi-cylindrical. member 5 that has laterally-extending flange-Incl bers 6 and inwardly-extending tongues 7, the latter freely engaging vertical grooves made along the peripheral side of the said Serial No. 542,701.

vertical portion of the bar-arm 4. The

base-plate 10, that comprises a transverselycurved part, with suitablvthreaded bores 11 and 14- at its opposite ends, is provided with side notches 9 to receive the lower ends of said flange-members 6 of the slide-member 5, for anchoring-means in their vertical, reciprocating movements for linear-adjustmerit. The threaded terminal of the said vertical portion ofthe bar-arm 4: is carried by the internally-threaded bore 11 in the base-plate 10 in clamping-relation to the lower end of the meeting-rails 15 by means of the clamping-bolt 16 and thumb-nut arrangement 13. The predetermined position of the staples 2 and the inturned hook 3 will cause a diverging position of the meetingrails in open relation to each other (as shown in Fig. 1), to admit and exhaust the air-currents for ventilating purposes, as shown by the curvilinear-path of the arrowline 17 in Fig. 1. l

To eliminate an eventual frictional-engagement of the thumb-nut equipped bolt 13 with the glass-portion 18, the bore 14 in the base-plate 10 is in an inclined position to allow the thumb-nut 13 an angular-displacement t'or clamping purposes. The closure members or spacing-plates l9 and 20, interposed beneath or above the top and.

bottom rails of the respective upper and lower sashes, will cover all apertures created by the above-described adjustment.

The spacing device, seen in Figs. 6 and 7, is especially adapted for use in connection with our invention herein and is composed of a short member 19 (to the right), and a long member 19" (to the left), an open slot 22 being provided in the inner end of the member 19, and a metal plate '23 extend ing from the inner end of member 19 for engaging said'slot 22 in uniting the two members 19 and 19 for longitudinal extension or adjustment to suit different widths of window-openings and to allow the member 19 to be interchangeable, a longer or shorter member 19 being readily adapted to be detachably-c0nnected with the plate 23 when occasion requires. This spacingmember is not specifically claimed herein but it otherwise forms the subject-matter of a later application for patent.

Certain of the details of construction, shown herein, can be varied according to individual preference and special conditions Without departing from the spirit and essence of the invention as defined in the appended claim.

\Ve c1ai1n: 5 In a device 0f the character described, the combination with the meeting-rails 0i a Window, 01 a horizontal arm or basemember having screw-threaded orifices at its opposite ends, a right-angled bar-arm hav- 10 ing a guide-channel provided in its opposite vertical sides, a slide-member having flanges adapted to freely engage said channels, clamp-devices mounted on the said rightangled bar-arm, and means for regulating and sustaining the said clamp-devices in either open or in closed position, substantially is shown and described.
